Claiml. (Cl. '1M-112) The present invention relates to key operated card punching machines, and more particularly to machines for notching perforated cards along their marginal areas.

In the notching of cards having rows of holes along their marginal areas, an objectionable sliver or tab of card stock remains when adjacent holes are notched out by devices heretofore employed. Accordingly, it is an object of the present invention to provide an apparatus for notching adjacent holes in c'ards without allowing intervening stock to remain.

A further object of the invention is to provide a key-punch machine in which the number of punchesrequired to perform the complete card punching operation is considerably reduced.

Still a further object of the invention is to provide a punch arrangement for notching perforated cards in which the individual punches have a greater width than heretofore employed. Another object of the invention is to provide an improved key operated punching machine oi simpler construction than heretofore provided, in

which the number of operating parts i'or performing the punching operation is substantially reduced.

In its general aspects, the invention contemplates a plurality of individual die blocks and associated punches, in which the punches are arranged to notch intermediate or alternate perforations along the marginal areas oi a single or multiple row of holes in a card or check. Each punch has a width equal to or slightly greater than the pitch or spacing distance of the holes in the card marginal areas. Only about one-half the number of punches heretofore required for perforating the entire series of iields along the card margins is required, since the punches operate on only alternate peri'orationsV during their actuation toward the die portion of the apparatus. Following such perforations, the punches are shifted along the marginal edge of the card a distance equal to the pitch between the perforations or holes in the margins of the cardand another punching actuation takes place. By virtue of this arrangement, the punches may be made of a width equal to or slightly greater than the pitch spacing distance between the card perforations. thus eliminating the sliver or tab of card stock that would remain between adjacent perforated holes punched simultaneously by parallel punches.

The machine is designed for operating a plurality of individual diel blocks and associatedpunches during the cycle of operation lof the card, the notching being preselected bythe derpression of keys in a full keyboard bank prior to actuation of the apparatus to effect movement of the punches toward their female die member. The keyboard and its associated mechanism are so constructed and arranged as to cause certain of the punches to produce either a'shallow notch to the first row of perforations in cards having multiple rows of holes or a deep notch therein, as required.

One form which the invention may assume is A exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a top plan view of a machine for punching cards having rows of holes along their marginal areas, portions of the outer housing or covering having been removed to disclose the interior mechanism.

Fig. 8 is a view similar to Fig. 7, disclosing the punches shifted along the edge of the card and along the selector members a distance equal to the pitch between adjacent card perforations.

Fig. 9 is a partial plan view of a notched card.

Fig. l0 is a diagrammatic View representing the time relationships of the dilerent parts of thel mechanism during a complete cycle of its operation.

In the machine disclosed in the drawing, a punch and die mechanism is provided for selectively notching the marginal areas of cards from the outer edge of the card to either an outer or inner row of perforations. In one type of perforated card, the marginal areas are divided into elds, each field being adapted'to be punched to one or more of its perforations to indicate a particular number. As an example, the card 3 I illustrated 'in Fig. 9, and adapted for use in the full keyboard machine illustrated in the drawings. contains ten fields` II along its longitudinal marginal portion,`each field having outer perforation I3, representing the number 7. 'is' placed in alignment with the number 4 perforation on a line perpendicular to the longitudinal edge f the card. i

By making a shallow notch from the edilel of the card to the number .1," 2" or 4 perforation, the corresponding nunberon the card is indicated. By making a deep notch in the card to the number "7" perforation. such corresponding number is indicated. Number "3 is notched in the card by notching both the number "1 and number 2" perforations; number "5" by notching the number 1" and number "4 perforations; and number "6" is obtained'by notching the number 2 and number 4 perforations. Number .8 is obtained by notching the number "1 and number "7 perforations, and number "9 is obtained by 'notching the number 2" and number "7" perforations. If no notching is performed in any particular field, that fact indicates the number 0. g

The machine includes an outer housing I4 and a base I 3 from which extends a pair of spaced vertical arranged side frames I6, I1. The forward portion of the housing is generally horizontal and constitutes a table I8 on which a card I0 to be punched may be placed, the inner marginal area of the card extending within the housing'for reception between the female die blocks I9, having slots arranged vertically or perpendicular to the edge of the card, and 'cooperable punches 2l which are pivotally mounted on the die blocks. as by pins 22 extending through the upwardly extending die block ears 23 and the lower rear portions of the punches. By pivotal movement about its pivot pin 22 in a downward direction, each punch 2| is brought into and out of cooperative relation with the associated cavity 20 in the die block I9.

The die blocks I9 and the punches 2 I disposed thereabove are individually movable in a direction perpendicular to the edge of the card I0. When disposed in full forward position over the card, a punch is in position for cutting a deep notch to the inner lnumber 7 perforation. When positioned in an intermediate location with respect to the card, the punch will cut a shallow notch at either the number 1," number "2 or 'number "4 perforation, and when disposed in a fully rearward position, the punch 2l will move clear of the card and will not eilect any notching at all during its movement toward the female die cavity 20.

The punches are alternately arranged with respect to the perforatons in the card. That is. punching can only be eected at alternate perforations or holes along the marginal area of the cards during downward actuation of the punches 2| toward the die block cavities 20. The punches and dies are mounted for sliding movement in a carriage 24 extending transversely across the machine and having one extension 25 slidably mounted in one of the side frames I1 and a second extension 26 slidably mounted in the other side frame I6, extending outwardly therefrom.

tions of each slidable selector member.

4. The entire carriage is shiftable transversely in order to shift the punches 2l and dies Il a distance equal to the center to center distance between adjacent perforations I2 along the margina-of the card as described hereinafter.

The carriage 24 is provided with forward and rearward uprights 21, 2l on which the punch and die blocks I9 are slidably supported. Each die block has a forward extension 29 projecting through a slot 3l in the forward carriage upright 21, and also a rearward extension 3l extending through a slot 32 in the rear carriage upright 2 3. Each die block and punch is urged in a rearward direction by a spring' 33 having one end secured to a suitable pin 34 on the carriage 24 and its other end attached to the die block itself.

The extent of rearward movement of each die block I9 is determined by engagement of its rearward extension 3| with an aligned lug 36 whose position is selected in accordance with the depression of a key 31 on the keyboard 'Ihe lug I6 may occupy a vposition indicated by the dotted line C (Figs. 2, 7 and 8), which allows the spring 33 to move the associated die block I9 and punch 2| to its fullest rear position and place the' associated punch completely out of disposition over the card I0, so that its downward actuation cannot effect notching of the card. The lug 36 may be moved forwardly to an intermediate position indicated by the dotted line B, in which the punch extends over an outer perforation I2 to eiect a notching of either the number 1, 2" or 4" perforation. or the lug may be positioned forwardly to coincide with the dotted line A position, in which the punch 2I is disposed forwardly to notch deeply over the number 7 perforation. In all instances the springs 33 tend to move the die blocks I9 and punches 2l to their full rearward positions; their forward movement against the spring actions being produced by a transverse bar 36 engageable with the rear sides of the forward die block extensions 29.

Positioning of the lugs 36 and slidable die blocks I9 and punches 2| are determined selectively by appropriate depressions of the keys 31 in the keyboard; As disclosed in the drawings, there are ten columns of depressible keys, each column of keys having numbers ranging from 1 to 9 along the inclined housing face. Depression of each key effects a corresponding positioning of the lugs 36 and determines the extent of rearward movement of the die blocks I9 and punches 2l, thereby appropriately disposing the die blocks and punches with respect to the card I0 placed on the table I8. Eachkey 31 forms the upper part of a key stem 39 movable vertically within the machine frame and having one or more inclined cam surfaces 40 adapted to cooperate with one or more horizontal sliding selector members 4I on whose forward ends the lugs 36 are provided. The sliding members are guided for movement within the frame of the machine by appropriate guide pins 42 extending through horizontal slots 43 in the forward and rear por- Rearward movement of each selector member 4I is accomplished by a spring 44 attached to the machine frame and to the rear of the sliding member, while its forward movement is determined by depression of a key 31, which will cause its inclined cam surface 40 to engage a follower pin 45 on the sliding member and move the latter in a forward direction.

This stud 6| is alsoadapted to engage a. cam surface 64 on the underside Aofthe link. Rotation .of the shaft 33 and disk 82 in a forward direction has no eii'ect on vshifting the bail shaft 51 rearwardly. However, return rotation of thema'in shaft carries the disk 92 in a counter-clockwise direction (as seen 'in lfllig. 4) and engages the stud 8i in the recess 99 on the link 58, shifting the latter'rearwardly and causing the bail 54 to move all of the lock slides. rearwardly to 4free them from .the key stem -pins 48 and allowing the return springs 53 .to re-elevate the stems 39.

In addition, the number 8 key stem has cams 40, 40a engageable with pins 45 for actuating both the upper number 1" slide 4ia and the lower number 7 slide 4Ic, its lower cam sur face 40a being inclined to the same extent as the cam surface on the ,number 7 key; while the cams on the number 9 key stem operate -on pins on both the number 2 slide 4ib and the number 7 slide 4| c. Depending upon the depression of the key 31 in a particular column, the lugs 39 on the forward portions of the slides 4i are appropriately positioned, being moved to either the A, B or C position (Figs. 2, 7 and 8), and controlling the extent of rearward movement of an associated die block extension 3| under .the influence of its spring 33.

The keys 31 are held in their depressed position by a latch mechanism. Each key stem 39 in a column has a laterally extending pin 46 adapted to engage against an'inclined .cam surface 41 on a lock slide 48 mounted for forward and rearward movement .along the frame by for-- ward and rearward guide pins 49 secured to the frame and ext-ending through slots 59 in the latch or lock slide 48. The depressed :key stem 39 causes its pin 4B -to engage against the cam surface 41 and move the slide rearwardly, which permits the pin 4B to move olf the cam surface and enter a latch recess 5| between the cam p0rtion of the slide and the slide body itself. Following such entry, a spring 52 secured to the frame and slide 48-moves the latter forwardly to dispose its cam 41 over the pin 46 and prevent ele- Following release oi the key stems 39 and as the link 58 continues its rearward movement, a

cam surface on a cam projection 65 of the link engages a stationary stud 63 attached to the side frame. causing .the link 58 to be elevated to `re- .movethe lug recess 0 completely from engagement by the disk stud 8i, allowing the spring 59 to again move the link forwardly and place the bail 54 and the lock slides 48 in their forward positions, in which the depressed key stems 39 can again be locked.

During the cycle of operation of the machine.

all die blocks i9 and the punches 2| pivoted thereon are moved in a forward direction by the transverse bar 38 engaging the rear portions of the forward die block extensions 29. This bar is thenmoved rearwardly. to permit engagement of the rearward die block extensions 3| with aligned lugs 38 on the horizontal selector members 4I. Movement of the bar 38 is determined by motion of the main shaft 53.

The bar 33 is secured to a pair of spaced arms 61 attached to a shaft 68 journalled in the side frames I6, I1 of the machine'. One of the arms is connected. by a rod or link 69, to another lever arm 10 oscillatable on a s haft 1l extending across the machine frame, this latter arm having a follower roller -12 at 4its upper end engageable with a cam 13 secured to the main shaft. During the motion of the mainshaft, the cam 13 engagesl the follower roller 12 and, through the arm 19, link B9 and forward arms 61, appropriately moves the transverse bar 38 and the die blocks I9 engageabie therewith in a forward direction. A low peripheral area 13a in the cam permits the springs 33 to shift the die blocks I9` and bar 38 rearwardly.

As stated above. alternate perforations may be notched, whereupon the entire carriage 24. with i the die blocks i9 and punches 2l mounted there'ifi vchine by studs or pins 11 ilxed to the frame and slidable within horizontal guide slots 18. The

slide 16 has a pair of spaced, vertically arranged arms 19, 89 whose opposed vertical surfaces are engageable at proper sequences in the cycle of operation of the machine by a stud or follower roller 8| mounted on the end of a lever arm 82 fixed to the main shaft 63 of the machine. When the stud 8| engages the forward arm 19. the roller 15 is positioned inthe cam slot 14 to hold the carriage 24 to the left of the machine (as seen in Fig. 1). Rotation of the lever 82 with the main shaft 63 until the lever engages the other vertical arm 80 will effect rearward shifting of the slide 16 and positioning of the carriage 24 to the right (as seen in Fig. 1), shifting the die blocks |9 and their punches 2| a distance equivalent to the distance between perforation centers in the outer row |2 of card perforations and also from one group of 'alternate selector member lugs 36 to the adjacent selector member lugs.

The slide 16is held in the position to which it has been moved by the shaft 63 and lever arm 82 by a suitable detent consisting of a lever 88 mounted on a fuicrum pin 84 and having a roller 85 adapted to engage on either side of a triangularshaped slide projection 86,*the roller 85 being urged upwardly into engagement with the slide i6 and its projection 86 by a spring 81 attached to the other end of the detent lever 83 and to the frame. The slide 16 is prevented frominadvertent rearward movement upon engagement of the roller 85 with the rear side of the projection 86, and is prevented from unintentional forward movement upon engagement of the detent roller 85 with the forward side of the projection 88.

The punches 2| are rocked on their pivot pins 22 toward and from the die block cavities 20 at proper times in the cycle of machine operation. Such actuation occurs as a result of downward and upward movement of a bail shaft 88 extending across all of the punches and positioned within their horizontal slots 89 (see Fig. 3). The ends of the bail shaft88 are connected to opposed arms 90 mounted on a shaft 9| extending across the machine. One of the lever arms 98 has an arm extension 92 projecting rearwardly from the shaft 9| and mounting a follower roller 93 on its rearward end ridable upon a cam 94 xed to the main shaft 63 of the machine and upon its radial cam lobe 95 for actuating the punch 2| in an upward and downward direction. As explained below, each punch 2| is actuated twice during each cycle of the machine operation.

The main shaft 68 of the machine may be rotated in both counter-clockwise and clockwise "directions by any suitable means, either manually or by a motor (not shown). The main shaft extends from the frame of the machine where an operating handle 96 is suitably secured thereon. This handle is moved forwardly against the action of a spring 91 attached to the frame and to a lever arm 98 secured on the main shaft 53, the spring serving to move the shaft 63 back to its initial position, as determined by engagement of the lever 98 with a stop or limit pin 99 mounted on the side frame |1 of the machine. Forward movement of the main shaft is also limited by engage- 8 ment of the lever 98 with another stop pin ill. Actually the shaft I3 is rotatable through about 90". in accordance with the specific design shown in the drawings.

At the start of the operation of the keypunch machine. the'transverse bar 3l is in a forward direction. holding all of the die blocks I8I and punches 2| in their extreme forward positions. The keys 81 are appropriately depressed in the keyboard in order to'preselect all of the desired fields on the card ||I to be notched, the sliding members 4| being moved by the depressed key stems 39 to appropriately position the lugs 36. Let it be assumed that the number 39" is to be notched along the marginal portions of a card i8 placed on the table |8 of the machine. The number "3" key in one column is depressed and also the number "9 key in the next adjacent column. Depression of the number "3 key moves the number "1 slide 4|a and the number "2" slide 4|b forwardly to shift their lugs 38a, 38h to the B position. Depression of the number 9" key in the next key column moves the number "2 slide 4|b for that column forwardly to place its lugs 36h in the B position and moves the iowermost slide 4|c forwardly to its extreme position to place its lug 38e in the A position. The keys and slides are held in such position by the lock slide cams .41 engaging over the pins 45 projecting from the key stems 89. j

During the initial movement of the operating and main shaft 83 in a forward direction, the bar 38 is shifted rearwardly by the springs 33 attached to the die blocks I9, because of the rotation of the cam 13 to permit the roller 12 to move inwardly into the smaller diameter cam portion 13a. This rearward movement of the die blocks I9 and their associated punches 2| is limited by engagement of the rearward extension 3| of each die block with an associated lug 38. As indicated in Fig. 7, the number 1 lug 36a is engaging the number "1" punch die I9 in the first column in which the number 3 key has been depressed, and the next adjacent punch die I9 has engaged the number "2 lug 38h in the next adjacent key column. It is to be noted that the punch dies are engaging only alternate lugs across the machine, there being no die engagement with the number 2 lug 36h in the rst column or the number "7 lug 36e in the second column.

The detent 83, 85 is maintaining the slide 18 in its forward position to hold the carriage 24 in its left position, and thus hold all of the punches 2| and die blocks |9 in their left positions. As the motion of the main shaft 83 continues upon forward operation of the hand lever 98, the cam lobe '95 on the punch cam 94 engages the lever 92 and moves the bail shaft 88 downwardly to move all of the punches 2| toward the die cavities 28. However, since only the number "1" punch and the associated number 2 punch referred to above have been positioned by their lugs 38a, 36h in punching relation with respect to the card only those two punch members move downwardly to punch the card in adjacent fields by removing the card stock to the number "1 and number 2" perforations. respectively. As the forward movement of the main shaft 63 under the influence of the operating lever 498 continues, the cam lobe l-9-'5 rides off the follower 93 and allows the spring lili. attached to the lever y82. to move the punches 2| upwardly out of the card |0 The large periphery of the transverse bar actuating cam 13 again comes into play to engage the roller 12 and again move the bar 38 forwardly to shift Vnow at its initial position for all of the die blocks I8 and punches 2| in a forward direction, the lever arm stud 8| then engaging the rearward arm 80 to eilect shifting of the |8- in alignment with the next adjacent selector lugs 38 (see Fig. 8).

The operating lever 88 and associated main shaft 83 then begin their return motion under the influence oi' the return spring 81. The small diameter portion 13a of the bar actuating cam 13 is again positioned adjacent the roller 12, which permits the springs 33 to reposition the die blocks I 9 and punches 2| rearwardly to limits determined by engagement of the rearward die block extensions 3| with the lugs 38. From an inspection of Fig.- 8, it will be evident that the punch dies I9 have been shifted a distance equal to that between adjacent perforations l2 and that the rearward lextension 3| on one die has engaged the number 2 lug 38h in the first column, which is at the B position, while the adjacent punch die has engaged the lug 38c in the next column corresponding to the C position, which is the posivtion determined by the number "7 slide`4|c which has been shifted forwardly by the number "9u key.

As the shaft 83 continues its rearward motion, the cam lobe 85 again engages the follower roller 83 on the punch bail operating arm 92 and again moves the punches 2| downwardly to notch the number 2 perforation in the first field and the number "7 perforation in the next adjacent field. The continued movement of the operating lever 86 and shaft 83 in the rearward direction again causes the cam lobe 95 to ride oil? the punch follower roller 83 and allows the return spring ||II to re-elevate all of the punches 2|. During the last portion of the return movement of the shaft 63, the stud 8| on the latching disk 82 engages the lug 60 recess on the link 58 and moves the lock bail 54 rearwardly, to shift all lock slides 48 rearwardly and move their cams 41 oH- the cooperable pins 4S, allowing the return springs 53 to re-elevate the keys 81 and key stems 39. As aforementioned, continued movement of the link 58 in a rearward direction cames its cam 85 to engage the fixed stud 88 and removes the lug recess 50 from engagement with the stud 8|, permitting the return spring, 58 to move the link 58 forwardly and allow the slide springs V52 to shift the lock slides 48 forwardly to a position wherein they may again lock depressed key stems 39 in position. During the last portion of the return movement of the main shaft 83, the carriage 24 is again shifted to the left by engagementof the lever arm stud 8| with the forward slide arm 18 and the bar 38 shifted forwardly to move all dies I9 and punches il forwardly. The machine is appropriately punching another card in accordance with the selections of the keyboard. e y

Attention is directed to the Fig. l time chart, representing the cyclic relationships between the positions and operations of the lever'98, main shaft 53. keys 31, carriage 24, bar 38 and bail shaft 88. This chart is believed to be self-em planatory.

It is to be particularly noted that only alternate perforations along the margins of the card are subject to notching during the forward movement of the main shaft 63 andthat the intervening perforations are subject to notching during the return motion of the operating shaft. In view of the fact that adjacent perforations need not be notched simultaneously. it is possible to employ punches 2| having a width equal to the distance between perforations in any card row I2, and, for that matter, the punch width may be made actually greater than this pitch distance. As a result, the notching of adjacent perforations, as for exl ample in notching for number "3 or number 9 in the example indicated above, eil'ects a complete removal of the card stock and does not allow an objectionable sliver to be produced as in prior devices. This is also true in the notching of perforations in adjacent fields, as indicated by the notching oi the number 1 perforation in the first field and in the deep notching of the number 7 perforation in the next adjacent field, in the example above cited.

It is also apparent that the notching of alternate perforations requires the employment of only about one-half the number of punches. The marginal fields of the card to be notched are preselected on the keyboard,`and the appropriate punchings of the desiredflelds takes plac'e during both the forward and rearward rotating motion of the main shaft under the influence of the handle ora motor mechanism (not shown).
